Lots of fun! These are really very very tiny. The smallest thing it is probably possible to knit.

It is quite fiddly to increase in the first two rounds. I found it helped to cast on loosely over two needles held side to side. I then kept the knitting quite loose for the second row of decreases. After that it is very easy and, well, nearly finished. Very cute :-)
